Key Takeaways
- Idaho recognizes the PLLC as a distinct entity type for licensed professionals (Idaho Code §30-25-201 (Uniform Business Organizations Code); professional-entity provisions at Title 30, Ch. 21, Part 9)
- Idaho does not require licensing board pre-approval as a condition of filing
- Filing fee: $100 online / $120 by mail
- Yes, more than most states. Idaho's "allied professional services" doctrine lets a PLLC combine professions that are frequently offered in conjunction with one another as parts of the same service package — unless a specific profession's own ethics rules prohibit the combination.
- LLC Attorney does not form PLLCs or other professional entities — this guide is educational; where your profession permits a standard LLC or corporation, LLC Attorney can form that
If you're one of the 19 licensed professions Idaho recognizes for this purpose — architects, physicians, attorneys, engineers, and similar occupations — Idaho law lets you form a Professional LLC, with a closed list that doesn't extend to other licensed occupations.
This guide covers exactly how to form an Idaho PLLC in 2026 — the state's closed 19-profession list, why there's no licensing-board sign-off required before filing, the $100 cost, and the specific $100,000/$300,000 malpractice-insurance requirement Idaho imposes on attorneys.
What Is a Idaho PLLC?
A Professional Limited Liability Company (PLLC) is a special LLC designation for licensed professionals — doctors, lawyers, accountants, and similar occupations. It works like a regular LLC, but ownership is restricted to people who hold the same professional license, and formation often requires sign-off from your licensing board before the state will accept your filing.
Yes. Idaho recognizes the PLLC as a distinct entity type for licensed professionals (Idaho Code §30-25-201 (Uniform Business Organizations Code); professional-entity provisions at Title 30, Ch. 21, Part 9).
Who Needs a PLLC in Idaho?
Idaho limits the PLLC to exactly 19 professions, and no others: architecture, chiropractic, dentistry, engineering, landscape architecture, law, medicine, nursing, occupational therapy, optometry, physical therapy, podiatry, professional geology, psychology, certified/licensed public accountancy, social work, surveying, and veterinary medicine.
Any licensed occupation outside Idaho's closed 19-profession list — real estate brokers or insurance agents, for example — simply forms a standard LLC; there's no PLLC option available to them because the list is exclusive, not illustrative.
Do I Need Licensing Board Approval First?
Idaho's Certificate of Organization for a PLLC is self-certifying — the organizer states the profession(s) being practiced and confirms the members are duly licensed directly on the certificate, without a separate board-issued certificate attached to the filing.
Because there's no pre-filing board sign-off, an Idaho PLLC exists as a legal entity as soon as the Secretary of State accepts the certificate — typically about a week for standard processing, faster with the expedite fee — but your board's ongoing licensure rules, and for attorneys the malpractice-insurance rule, still apply independent of that filing speed.
How to Form a Idaho PLLC
- Filing agency: Idaho Secretary of State
- Form: Certificate of Organization – Professional Limited Liability Company
- Filing fee: $100 online / $120 by mail
- Processing time: About 1 week for standard processing
- Expedited option: $40 for expedited (same-day to next-business-day) processing
- Name requirement: Must place "P" immediately before the entity abbreviation or the word "Professional" before the entity words — e.g., "PLLC," "P.L.L.C.," or "Professional Limited Liability Company"
Who Can Own a Idaho PLLC?
Members and managers actually rendering the professional service must be duly licensed in that profession — but Idaho doesn't require every single member to share an identical license if the PLLC is practicing "allied professional services."
Yes, more than most states. Idaho's "allied professional services" doctrine lets a PLLC combine professions that are frequently offered in conjunction with one another as parts of the same service package — unless a specific profession's own ethics rules prohibit the combination.
What Liability Protection Does a PLLC Actually Provide?
A PLLC protects you from business debts and from a co-owner's malpractice — but it never shields you from your own malpractice. If you personally provide negligent professional services, you remain personally liable for that regardless of the entity structure.
An Idaho PLLC shields members from each other's malpractice and from ordinary business debts, but never from a member's own negligent professional acts — that liability follows the individual professional regardless of the entity wrapper.
Idaho is one of only two states that require attorneys specifically to carry malpractice insurance — $100,000 per occurrence and $300,000 in the aggregate, under an Idaho State Bar rule in effect since 2018 — regardless of whether the practice is organized as a PLLC. No comparable blanket malpractice-insurance mandate exists for Idaho's other 18 PLLC-eligible professions tied to formation itself.
How Is a Idaho PLLC Taxed?
By default, a PLLC is taxed exactly like a regular LLC — pass-through to the owners' personal returns, with the option to elect S-corp or C-corp taxation if that fits your situation better. The professional designation changes ownership eligibility and licensing oversight, not the default federal tax treatment.
Idaho has moved to a flat personal income tax rate (5.695% as of the 2025 tax year), so an Idaho PLLC's pass-through profit is taxed at that rate at the state level, on top of federal income and self-employment tax under the default pass-through treatment.
Idaho PLLCs file a free annual report with the Secretary of State each year by the end of their anniversary month — there's no dollar fee for the report itself, just a filing requirement to stay in good standing.
How to Set Up Your Idaho PLLC Step by Step
If You Do It Yourself
Step 1 — Confirm you need a PLLC (not a plain LLC) for your profession.
Idaho limits the PLLC to exactly 19 professions, and no others: architecture, chiropractic, dentistry, engineering, landscape architecture, law, medicine, nursing, occupational therapy, optometry, physical therapy, podiatry, professional geology, psychology, certified/licensed public accountancy, social work, surveying, and veterinary medicine.
Step 2 — Get licensing board sign-off if required.
Idaho's Certificate of Organization for a PLLC is self-certifying — the organizer states the profession(s) being practiced and confirms the members are duly licensed directly on the certificate, without a separate board-issued certificate attached to the filing. Because there's no pre-filing board sign-off, an Idaho PLLC exists as a legal entity as soon as the Secretary of State accepts the certificate — typically about a week for standard processing, faster with the expedite fee — but your board's ongoing licensure rules, and for attorneys the malpractice-insurance rule, still apply independent of that filing speed.
Step 3 — File your formation documents.
File the Certificate of Organization – Professional Limited Liability Company with Idaho Secretary of State, $100 online / $120 by mail.
Step 4 — Appoint a registered agent.
Idaho calls this role a "Registered Agent" — required at formation.
Step 5 — Confirm ownership eligibility for every member.
Members and managers actually rendering the professional service must be duly licensed in that profession — but Idaho doesn't require every single member to share an identical license if the PLLC is practicing "allied professional services."
Step 6 — Address malpractice insurance requirements.
Idaho is one of only two states that require attorneys specifically to carry malpractice insurance — $100,000 per occurrence and $300,000 in the aggregate, under an Idaho State Bar rule in effect since 2018 — regardless of whether the practice is organized as a PLLC. No comparable blanket malpractice-insurance mandate exists for Idaho's other 18 PLLC-eligible professions tied to formation itself.
Step 7 — Handle ongoing state compliance.
Idaho PLLCs file a free annual report with the Secretary of State each year by the end of their anniversary month — there's no dollar fee for the report itself, just a filing requirement to stay in good standing. Idaho has moved to a flat personal income tax rate (5.695% as of the 2025 tax year), so an Idaho PLLC's pass-through profit is taxed at that rate at the state level, on top of federal income and self-employment tax under the default pass-through treatment.
Step 8 — Watch for Idaho-specific PLLC traps.
The most common Idaho-specific mistake is assuming the PLLC option is available to any licensed profession — Idaho's list of 19 professions is explicitly closed ("and no others"), so a licensed occupation not on that list, however similar it may seem, simply isn't eligible and must use a standard LLC instead.
